The friends are ready to try a problem. A battery has an emf of 12.0 V and an internal resistance of 0.05 Ω. Its terminals are c

Zanzabum

Answer:

Terminal voltage = 11.5 V

Power across load = 119.7 W

Power across internal resistance = 5.4 W

Power delivered by battery = 125.2 W

Explanation:

The current in the circuit is given by

$I=\dfrac{E}{R+r}$

where E is the emf of the battery, R us the load resistance and r is the internal resistance.

$I=\dfrac{12}{1.1+0.05} = 10.43 \text{ A}$

The terminal voltage is the potential difference across the load resistor.

V = I × R = 10.43 A × 1.1 Ω = 11.5 V

The power across any resistance is given by $I^2R$

For the load resistor,

$P_L=10.43^2\times1.1 = 119.7 \text{ W}$

For the internal resistance,

$P_r=10.43^2\times0.05= 5.4\text{ W}$

The power delivered by the battery is

$P = P_L + P_r = 119.7 + 5.4 = 124.1 \text{ W}$

This could also be found by

$P = IE = 10.34\times12 = 125.2 \text{ W}$

The discrepancy in both answers is due to the approximations. The second answer is better.

An infinite plane lies in the yz-plane and it has a uniform surface charge density.

Allisa [31]

Answer:

<u>So the correct answer is letter e)</u>

Explanation:

The electric field of an infinite yz-plane with a uniform surface charge density (σ) is given by:

$E=\frac{\sigma }{2\epsilon_{0}}$

Where ε₀ is the electric permitivity.

<u>As we see, this electric field does not depend on distance, so the correct answer is letter e)</u>

I hope it helps you!
